HINGE DEVICE FOR PORTABLE WIRELESS TERMINAL

摘要

A hinge device of a mobile terminal is provided to enhance users' convenience by performing various opening/closing operations by the second housing on two rotational shafts. A hinge shaft(202) includes a hinge protrusion(221) formed at one end and protruded toward one end of a hinge housing(201) and a shaft protrusion(223) extended in a longitudinal direction at the other end, and is rotatably received into the hinge housing(201). A hinge cam(203) includes the first plane(231d) and the second plane(231a) extended in a circumferential direction at its section facing the hinge shaft(202), and is received to be moved linearly in a longitudinal direction in the hinge housing(202). The first plane(231d) and the second plane(231a) have a step with a certain width and are connected by a pair of slope face(231b). A spring(204) provides elastic force in a direction that the hinge shaft(202) and the hinge cam(203) are attached in the hinge housing(201).
